一、在initinstance中加入:
word wversionrequested;
wsadata wsadata;
int err;
wversionrequested = makeword( 2, 2 );
err = wsastartup( wversionrequested, &wsadata );
if ( err != 0 )
if ( lobyte( wsadata.wversion ) != 2 ||
hibyte( wsadata.wversion ) != 2 )
二、在oninitdialog中加入：
m_socket=wsasocket(af_inet,sock_dgram,0,null,0,0);
if(invalid_socket==m_socket)
sockaddr_in addrsock;
addrsock.sin_addr.s_un.s_addr=htonl(inaddr_any);
addrsock.sin_family=af_inet;
addrsock.sin_port=htons(6000);
if(socket_error==bind(m_socket,(sockaddr*)&addrsock,sizeof(sockaddr)))
if(socket_error==wsaasyncselect(m_socket,m_hwnd,um_sock,fd_read))
return true;
三、#define um_sock wm_user+1
四、響應um_sock訊息：
onsock(wparam wparam,lparam lparam)
phost=gethostbyaddr((char*)&addrfrom.sin_addr.s_un.s_addr,4,af_inet);
//str.format("%s說 :%s",inet_ntoa(addrfrom.sin_addr),wsabuf.buf);
str.format("%s說 :%s",phost->h_name,wsabuf.buf);
str+="/r/n";
getdlgitemtext(idc_edit_recv,strtemp);
str+=strtemp;
setdlgitemtext(idc_edit_recv,str);
break;}}
五、傳送處：
dword dwip;
cstring strsend;
wsabuf wsabuf;
dword dwsend;
int len;
cstring strhostname;
sockaddr_in addrto;
hostent* phost;
if(getdlgitemtext(idc_edit_hostname,strhostname),strhostname=="")
else
addrto.sin_family=af_inet;
addrto.sin_port=htons(6000);
getdlgitemtext(idc_edit_send,strsend);
len=strsend.getlength();
wsabuf.buf=strsend.getbuffer(len);
wsabuf.len=len+1;
setdlgitemtext(idc_edit_send,"");
if(socket_error==wsasendto(m_socket,&wsabuf,1,&dwsend,0,
(sockaddr*)&addrto,sizeof(sockaddr),null,null))
